Plasticizers for Biopolymer Films - Glass Transition and
Plasticizers are low molecular weight agents added to polymeric materials such as plastics, biopolymer based films, paints, or adhesives, to produce or promote plasticity, flexibility, processability and to reduce brittleness by lowering the glass transition temperature (Tg).
Natural-based plasticizers and biopolymer films: A review
Plasticizers, for biopolymer-based films, can be divided into water soluble and water insoluble [25]. The type and the amount of plasticizer strongly affect the film formation from polymeric aqueous dispersions [26]. Hydrophilic plasticizers dissolve in the aqueous medium when they are added to polymer dispersions and if added in high
Biopolymer film: An alternative to single-use plastic food
Our research project produces biopolymer film from sustainable raw materials, advocating the green and sustainable approach in food production. It provides a non-toxic alternative to single-use plastic food packaging, and can be used in packaging fruits, dried food, oil and more. Its high biodegradability allows for simple disposal.
Biopolymer-based edible films and coatings for food
The biopolymers used for the development of films or coatings have been extracted from renewable, low-cost, and nontoxic sources which are easily degradable ( Dhanapal et al., 2012, Dhumal and Sarkar, 2018 ).
Natural-based plasticizers and biopolymer films: A review
In biopolymer-based lms and coatings production, plasticizers are also essential additives since they can im-prove exibility and handling of lms, maintain integrity and avoid pores and cracks in the polymeric matrix [20]. Incompatibility is commonly evidenced by phase separa-tion between the biopolymer and plasticizer, presented
- Who makes plasticizers in Egypt?
- ISC is the first specialized plant to produce a wide range of plasticizers in Egypt. With more than 35 years of experience in the chemical industry, ISC plant started production in 2022 to become the latest manufacturing plant to join AMAGO GROUP, which started its business in the chemical industry field in 1989 in Egypt.
- Are biopolymers hygroscopic?
- Usually, biopolymers and plasticizers are hygroscopic and therefore film moisture content is affected by ambient conditions. Besides, water is the main solvent in the natural biopolymer technology. Its molecules reduce the Tg and increase the free volume of biomaterials, and thus are considered as plasticizers.
- How many plasticizer exporters are there in Egypt?
- As per the Volza's Egypt Plasticizer Exporters & Suppliers directory, there are 1,070 active Plasticizer Exporters in Egypt exporting to 1,277 Buyers.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
